In this July 23, 2005 file photo, overall leader Lance Armstrong, of Austin, Texas, crosses the finish line to win the 20th stage of the Tour de France cycling race, a 55.5-kilometer (34.5-mile) individual time trial looping around north of Saint-Etienne, central France. Now Armstrong is getting back on his bike, determined to win an eighth Tour de France. The Tour "is the intention," Armstrong's spokesman Mark Higgins told The Associated Press, "but we've got some homework to do over there." AP Photo/Alessandro Trovati
